I have a '95 345 with the v-belt drive belt. Putting on a new belt and v-pulleys. How much pedal travel is there supposed to be before it begins to pull on the tensioner assembly to slack the belt? With the pulleys in the original locations, the pedal moves forward about 2" before beginning to move the tensioner.

You're going to have to be clearer --- for me anyway. What pedal are you talking about??

The brake pedal. When it is pressed forward/down, it releases tension on the drive belt.

That should not be the case. The brake on a 345 is internal to the transmission. Depressing the brake pedal shouldn't have any affect on the tension of the drive belt tensioning spring. The only connection between the two systems is the cross shaft that the brake pedal rotates is also the shaft that the drive belt tensioning spring clips to in order to provide drive belt tension. Rotating that shaft with the brake pedal should not affect drive belt tension at all.

I'm sitting here reading your reply and realized you are completely correct. I went through a 345 a friend let me have and after getting it back up to speed I started refreshing my GT275. It's that tractor I'm working on. I'll start another thread.
